Abstract
This study aims to assess the vulnerability of the community and its resilience
to flooding. The approach on feedback from the previous studies on flood risk in
Antananarivo city in combination with the KJ method is chosen as a methodology.
The passage of tropical storm ANA in January 2022 demonstrates that 1) flood risks
often occur in the city, but public perception of the risk remains low. 2) several
studies have assessed the flood risk in Antananarivo city; however, those studies
were not valorized by the Government and the different entities in charge of the
disaster risk reduction. 3) the findings of the KJ method highlight that the physical
factors and human factors were identified as the main issues for managing the flood
risk in Antananarivo city.
The water level of the Ikopa River increased by over 37.5m in January 2022 which
demonstrated the flood event in the city. This study outlines that the ability to
adapt to a natural disaster for the local population first depends on their standard
of living, especially in economic terms while for local authorities, it is manifested
in numerous adjustments. This study recommends the local Government to take the
flood disaster as a priority and provide training to the vulnerable community.
